' v10min. 11.15440 ticles generally, especially to cleaners used forscrubbing or cleaning greasy or extremely dirty therein so that theentire cleaning action is due to the abrasive action of the metallicwool. lf

soap or water is to be used in cleaningthe article, then an ordinaryragor brush is used to removel the dirt or grease from the article. Nocleaning article'upon the market today has efiectively combined anabrasive cleaning action-` rwith the use of .an emulsifying or cleaningagent,

such as soap.

vThe general Vobject of the'present inventionis to provide animprovedvcleaning article which is adapted to combine both an abrasiveand 'an on `the article to be cleaned. Y

- A further object of the present inventionv is to provide a tough butresilient cleaningl article which has a long life. z

A further object oi the invention is to provide a novel cleaning articleiromrcellular rubber and abrasive material.

The foregoing andother objects will be manifest from the accompanyingspeciiication'. reference being had of which: Figure 1 is a' transversesection of a cleaning article embodying the. invention, and a mold inwhich the articles are formed: and

Figures 2 and 3 are fragmentary detailsectional views. on Va largerscale, of other embodiments oi `the invention.

In the drawing-a cleaner or cleaning article Il is shown, which articlemainly comprises cel- T .i oFFICE is used te provide tneeruele In withan abrasive material Ifor removing grease o`r-large particles of dirtfrom an"article to be cleaned. The clean ing action oi the abrasive,stainless steel wool,

is aided by'soap and water which ordinarily will be used in conjunctionwith the cleaning article and which will be carried inthe cellularrubber. Hence, two types of a cleaning' action are combined by the useofthe cleaning article of the invention, whereasy such combinationhasnot been possible when using types of cleaners heretofore available.

The article I0 is made -in a suitable mold I6,-

the moldingcavity of which is first provided with a layer or skin ofrubber, or rubber-like substance by pouring a dispersion of suchsubstance into the 'mold and depositing a layer on the-mold surface. Theexcess dispersion is then removed` from the mold and stainless steelwool, which may be formed. to substantially the shape desired, isintroduced into the mold. Then before the gel oi rubber, or rubber likematerial is completely set up, aerated latex is poured into the mold anditilows around and illls up the space between the particles of stainlesssteel wool.

. Lastly the-latex is gelled and vulcanized to proto the accompanyingdrawing lular rubber Il, which has-intercommunicating cells andpreferablyv is made directly from latex by beating and/or aerating sameto form cellular rubber therefrom in accordance wlth'well knownpractice. The cellular rubber Il may be provided with a base l2 andwitha base ilange Il.

. A dense rubber skin 4I4 extends yover the sides and 'base of thecellular rubber body II. The cleaning article." also includes a mass' otstainless steel wool I5 which4 is embedded in the ycellular rubber I Iand which is made from a very soit, or annealed stainless steel. Thestainless steel wool with the disclosure inmy copending applicationySerial No. 370.791, illed December 19,1940;-

A modiiled cleaning article Ita, substantially the same as the articleIl, is shown in Figure 2.

4The article Illa has an impervious skin Ila thereon 'formed around acellular rubber core lla and `.has stainless steel wool Ila. embeddedtherein. The cleaning action of the article Ila is enhanced by abrasiveparticles II.` such "as pumice, which are embedded therein. -Theabrasive.. particlesshould be compounded in with the latex used intormingthe 'cellular rubber lla and in all events, are distributedthrough the cellular rubber .to provide a somewhat diiierent cleaningaction from that obtained solely by use o! stainless steel wool. Acleaning article. IIb, which has no impervious surface skinthereon butwhich otherwise is identical with the cleaning article il, il shown in`3, which cleaning article may bemost suitable for some purposes. In afurther modification ot the invention, a cleaner may bcmade'solely tromcellular rubber which has an impervious skin over a portion of thecleaner. Y v

It will be seen that a cleaning article having a waterproof yet ilexiblecovering over most of its surface is provided by the invention; Hence,the cleaner can be used by a person without getting the users hands wet.Also, the soap or other cleaningagent is only applied to one surface ofthe article whereby a savings is effected.. Use of an oil and grease4resistant rubber is especially desirable where the article is to be usedin cleanv from the scope of the invention as have been completelyillustrated and described herein, it will be appreciated that furthermodifications thereof may be made without departing appended claim. P

What is claimed is:4 v

A scrubbing cleaning article comprising a body of intercommunicatingcellular rubber, and abrasive niean's comprising a mass of soft,annealed stainless steel wool embedded in and extending through saidbody to reinforce the same and en- "hancethe cleansing action thereof,the body having a base portion, side portions and an exposed endportion, an impervious skin of a exible material bonded rto said baseportion and side portions, and said body having a base ange, whereby thearticle is adapted to be held comfortably in the hand of a user.
